Hello! I am new to having chickens into this forum. I have a chicken with a whitish goopy swollen eye and mucous in her beak that flies out when she shakes her head. No noticeable sneezing or coughing. Her bawk is a little off. I started giving her 800 mg of duramiacin in her water and Terramycin in her eye. She is isolated from the others. No one else shows sign of illness. I've had touble getting information. There is too much on the Internet. Please help if you can. I would greatly appreciate any advice. Thank you!
